Product description

2 pieces of Nano V3.0, ATmega328P microcontroller board, Nano Board CH340G chip 5V 16MHz with 2 245mm USB cables, compatible with Arduino Nano V3.0 for Arduino

Features:
This is a small and simple Arduino nano expansion board.
It will lead out all the Nano pins, it is convenient for us to wiring and experiment.
Great for temporary things you don't want to solder.
It provided a nice platform for wiring circuits to an Arduino Nano. It can be used in conjunction with or in place of a breadboard.
It lets you make a temporary circuit without the reliability issues you get with prototyping boards, but maybe need a bit more effort.
You need to use your Nano to hold the black pin headers straight and flat during soldering.

Size: about 2.21" x 1.65" x 0.50" (L* W* H)

Package Including:
5 *Nano Terminal Adapter Shield Expansion Board
